Red cell deformability in diabetics is much lower than that in normal controls. In patients with diabetic retinopathy, the decrease of red cell deformability is much more prominent than in patients without. Urinary albumin excretion rate in diabetic patients is inversely correlated with red cell deformability .The data above suggest that there is a close relationship between decreased red cell deformability and microangtopathy in diabetic patients

Objective To detect the expression of macrophage inlfammatory protein 1α(MIP-1α) in the myocardium of viral myocarditis (VMC) mice at different phases. Methods A total of 120 4-week-old male BALB/c mice were randomly divided into 2 groups, 80 in the VMC group and 40 in the control group. Mice in VMC group were inoculated intraperitoneally with coxsackievirus B3 to build VMC models, while mice in control group were treated with DMEM cultivate liquid. Ten mice of each group were sacriifced on days 3, 7, 15 and 30 after treatment and their heart tissues were collected for analysis. The level of MIP-1αin the myocardium was determined by immunohistochemistry. Myocardial histopathology was examined with hematoxylin and eosin stain. In addition, the relationship between the level of MIP-1αand the degree of myocardial lesion was investigated. Results The expression of myocardial MIP-1αprotein in VMC group was up-regulated in myocardium on day 3 after inoculation of virus, and slowly decreased after the peak on day 7, but still sustained a high level on day 30. Compared with the control group, the levels of MIP-1αin VMC group were increased signiifcantly at every phase (P<0.05). Furthermore, positive correlation was found between MIP-1αprotein expression levels and myocardial histopathologic scores in VMC group (r=0.94, P<0.01). Conclusion The up-regulated expression of MIP-1αmay play a critical role in the pathogenic mechanisms of viral myocarditis.

This paper discussed the importance and urgency of enhancing medical students' law education through analyzing the status of student' s knowledge on the medical law,changes in the environment of physician practicing and damages and disputes between the doctors and patients made by the student' s lawbreaking.Meanwhile,suggestions were proposed including establishing a law teaching group consisted of professional and pluralistic teachers,disseminating the law concept,adopting appropriate methods in appropriate periods.

Objective To study the relationship between the co‐expression levels of inducible costimulatory molecule (ICOS)and CD28 on peripheral blood CD4+ and CD8+ T cells and Behcet’s disease(BD).Methods Flow cytometry was used to detect the expression levels of ICOS and CD28 on peripheral blood CD4+ and CD8+ T cells of BD patients(n=22) ,including those with active BD(ABD ,n= 14)and stable BD(SBD ,n= 8) ,and of normal subjects(n= 22).Results The proportion of CD28+ ICOS+ CD4+ T cells was significantly increased in ABD patients when compared with normal subjects [(34.72 ± 12.87)% vs.(25.36 ± 8.24)% ,P<0.05].No significant difference was found in the proportion of CD28+ ICOS+ CD8+ T cells [(9.32 ± 4.57)% vs.(7.24 ± 3.36)% ,P>0.05]between the two groups.The proportions of CD28-ICOS+ CD4+ T cells and CD28-ICOS+CD8+ T cells were both obviously increased in ABD patients when compared with those in normal subjects[(2.54 ± 1.63)% vs.(0.76 ± 0.25)% for CD28- ICOS+ CD4+ T cells ,P< 0.05;(8.79 ± 3.41)% vs.(3.04 ± 1.25)% for CD28-ICOS+CD8+ T cells ,P<0.05].Conclusion The increased expression level of ICOS on peripheral blood CD4+ and CD8+ T cells is not closely associated with the expression of CD28 to some extent in BD patients ,suggesting that cells expressing only ICOS play an important role in the development of BD.

Dome-shaped macula (DSM) of high myopia has been described as an inward convexity or bulge of the macular within the concavity of the posterior staphyloma in highly myopic eyes,with the bulge height over than 50 μm,which can be observed by optical coherence tomography.There are three patterns of DSM,including the typical round dome,the horizontally oriented oval-shaped dome and the vertically oriented oval-shaped dome.The pathogenesis of DSM development remains unclear,several hypotheses have been suggested,such as localized choroidal thickening in the macular area,relatively localized thickness variation of the sclera under the macula,resistance to deformation of sclera staphyloma,ocular hypotony and tangential vitreoretinal traction.Vision-threatening macular complications of DSM including serous retinal detachment,choroidal neovascularization,foveoschisis and retinal pigment epithelial atrophy.Clinically,asymptomatic patients with DSM mainly take regular follow-up observation.Appears serous retinal detachment and significant visual impairment,treatment with half-dose photodynamic therapy,supplementary of laser photocoagulation or oral spironolactone may have a beneficial effect.However,more large clinical studies are required to confirm the exact efficacy of these treatments.

BACKGROUND:MicroRNA has tissue and cel specificity, and high expression of endothelial cel-specific microRNA-126 (miR-126) plays an important role in angiogenesis.
OBJECTIVE:To explore the effect of miR-126 on transplanted free flap survival and histological activity as wel as its mechanism in angiogenesis.
METHODS:Transient transfection technology was used to enhance the expression of miR-126 in bone marrow mesenchymal stem cel s. Expression levels of macrophage inflammatory protein-1α, tumor necrosis factor-αand vascular cel adhesion molecule-1 mRNA were detected by real-time PCR, and expression levels of ERK1/2, AKT, pERK1/2, pAKT protein were measured by western blot assay. Forty-eight Sprague-Dawley rats were randomly divided into three groups (n=16 per group), fol owed by preparation of abdominal free flap models. Rats in the three groups were given injection of miR-126 mimics-transfected cel s, miR-126 mimics control-transfected cel s and PBS 1 cm and 3 cm distal to the free flap, respectively.
RESULTS AND CONCLUSION:Expression levels of macrophage inflammatory protein-1α, tumor necrosis factor-αand vascular cel adhesion molecule-1 mRNA in the cel s transfected with miR-126 mimics were decreased by 36, 3.5 and 14 times compared with those in the PBS group, respectively. Expressions levels of ERK1/2, AKT, pERK1/2, pAKT protein in the distal free flap increased significantly in the miR-126 mimics group than the other two groups, as did the ratios of pAKT/AKT and pERK1/2/ERK1/2. In addition, the expression levels of macrophage inflammatory protein-1α, tumor necrosis factor-αand vascular cel adhesion molecule-1 protein in the flap tissue fluid were significantly lower in the miR-126 mimics transfection group than the other two group. Al these findings suggest that miR-126 can promote free flap survival by creating favorable conditions for angiogenesis in the free flap tissue.

Objective To study the clinical effects of breast-preserving surgery in early-stage breast cancer. Methods From March 2002 to March 2007, 27 cases of early-stage breast cancer were treated with breast-preser-ving surgery. The control group had 28 cases, treated with radical mastectomy. Survival rate and recurrence rate were observed. Results The short-term progress of breast-preserving surgery in early-stage breast cancer had no significant difference with that of radical mastectomy. Plastic effects of breast were satisfied. Conclusion Breast- preserving surgery in early-stage breast cancer had favorable effects both in progress and in plastic. Therefore, it is warranted for wide use.
